I'm using libxml-ruby 0.5.2 on Ubuntu 7.10 x64 with Ruby 1.8.6. I'm
trying to use the XML::Reader method expand to extract a full
XML::Node object when I find one my program is interested in. This
works OK except when Ruby tries to garbage collect the Node object
returned by Reader.expand. I get the following error:
[BUG] XmlNode Doc is not bound! (ruby_xml_node.c:1270)
I was able to reproduce this using the 'simple.xml' file in the
libxml-ruby test suite. Run the following code:
#!/usr/bin/env ruby
require 'xml/libxml'
rdr = XML::Reader.file("simple.xml")
rdr.read
rdr.expand
GC.start
rdr.close
The GC.start line will output the BUG message above then do a core dump.
The message from ruby_xml_node.c line 1270 comes from the
ruby_xml_node_mark_common function. Apparently the libxml xmlNode
object has a document associated with it, but that document doesn't
have a Ruby wrapper object associated with it.
I'm afraid Linux isn't my native development platform so I don't know
what if any additional debugging steps I can take, so I hope the code
above demonstrates the problem.
Thanks,
Adam
